That's what Obi-Wan said on the Death Star. I've always wondered how R2-D2 would have such capabilities, as decoding schematics and other top secret info doesn't really seem like it would fall within the usual requirements of an astromech. Why did Obi-Wan know or assume R2-D2 could traverse the computers of the Empire's most powerful superweapon? Is it because Obi-Wan remembers some of the upgrades Anakin had modified into him? Or is it simply because Leia fed him the new "codecs" or whatever to be able to read through such material.

What do you think?
